Sudip Kumar Mondal from Jadavpur University in Kolkata visited the University of Edinburgh through the HPC-Europa3 Transnational Access programme. Falling from 11 October to 29 January, Sudip's visit was unlike most others because the Covid pandemic was ongoing. In this blog post Sudip describes his experiences in coming to and working in Edinburgh.

My doctoral research focuses on the physical behaviour of naturally occurring mineral phases at high temperature and pressure conditions by employing quantum chemical simulations which are hard to realize through experiments at the laboratory. Dr Andreas Hermann, my supervisor at the University of Edinburgh, was undoubtedly perfect for supervising this project, being an expert on materials at extreme conditions.

Alexey Bobrick (Lund UniversitySpirit of 2020. My host and me, on one of the top floors in Birmingham University.(link is external), Sweden) was an HPC-Europa3 visitor hosted by Dr Silvia Toonen (link is external)at the Institute of Gravitational Wave Astronomy(link is external), University of Birmingham, UK. Because of COVID-19 restrictions, Alexey's visit has been split between his time in Birmingham (from 1–23 November), and working remotely from Sweden until 23 December. In this post Alexey tells us about his trip to Birmingham.

I study binary stellar astrophysics at Lund University, Sweden. In Birmingham my host, Dr Silvia Toonen, is one of the leading experts in triple and binary stellar evolution. I arrived at my accommodation in the middle of the autumnal Edgbaston Park area next to Birmingham University, and next morning I met my host. She kindly showed me around the campus and introduced me to her colleagues. The image shows me and my host, on one of the top floors in Birmingham University.  We then launched into many science discussions, which continued in the following weeks, together with meetings, work, calculations and more discussions.

UrgentHPC20 workshop at SC: Fighting disasters with urgent computing

Join the workshop: Friday 13 November, 2:30pm–6:30pm ET

At SC20 this year we are chairing UrgentHPC, the second international workshop on the use of HPC for urgent decision making. The idea of the workshop is to explore the fusion of HPC, big data, and other technologies in responding to disasters such as global pandemics, wildfires, hurricanes, extreme flooding, earthquakes, tsunamis, winter weather conditions, and accidents. Whilst HPC has a long history of simulating disasters, we believe that technological advances are creating exciting new opportunities to support emergency, urgent, decision making in real-time.

EPCC leads a work package of the VESTEC (Visual Exploration and Sampling Toolkit for Extreme Computing) project, which seeks to fuse HPC and real-time data for urgent decision-making for disaster response. Our work has resulted in two accepted papers into SC20 workshops: one around our custom workflow execution system, and another on extending the Common Workflow Language standard to better support parallel application execution.

On-demand computing and data solutions for industry at EPCC

Cirrus is a Tier-2 state-of-the-art advanced computing facility available to industry and academia. Hosted and managed by EPCC, it provides an ideal platform for solving computational, simulation, modelling, and data science challenges. 

The system was recently upgraded via a £3.5m funding award from the UK's Engineering and Physical Sciences Research Council. This included the addition of 144 NVIDIA V100 GPUs and a 256TB high-performance storage layer for the most demanding data-streaming applications. 

Optimising sparse-matrix vector multiplication on Intel Xeon Gold processors

Edoardo Coronado visited EPCC from 18th May–15th August 2019 under the HPC-Europa3(link is external) programme. Here he gives us an update on his research since his previous blog article.

During my visit to EPCC in 2019 under the auspices of the HPC-Europa3 programme, I worked on optimising routines to perform the Sparse Matrix-Vector (SpMV) product, a common operation in lots of scientific applications, on Intel Xeon Gold processors and Graphics Processing Units (GPUs).

VESTEC Project Poster at ISC 2020 digital conference

This week ISC, one of the largest conferences in the supercomputing calendar, should have been running in Frankfurt. It’s a funny feeling because, as I type, I realise that if it wasn’t for COVID-19 then, instead of being stuck at home, I would have been busy navigating the Messe Frankfurt, going from one session to another.

Rapid Assistance in Modelling the Pandemic (RAMP) initiative

I am the Project Manager of the Rapid Assistance in Modelling the Pandemic (RAMP) initiative, supporting Prof. Mike Cates and the RAMP Steering Committee. RAMP was convened by the Royal Society in the UK to enhance existing COVID-19 initiatives. The motivation was to enhance the modelling teams who inform Government policy through channels such as SPI-M (Scientific Pandemic Influenza Modelling Group), which reports to SAGE (Scientific Advisory Group for Emergencies).

Free introductory HPC and GPU courses: Edinburgh, 7-10 January 2020

EPSRC has recently announced the new Tier-1 ARCHER2 HPC service and is also in the process of extending the UK's Tier-2 HPC systems. This will give users access to substantial amounts of new CPU and GPU hardware, so it's a perfect time to learn about how to use parallel HPC systems and how to program GPUs.

A public UK HPC knowledge base

Photo by Glen Noble on UnsplashIn this blog post I consider how we (as the UK HPC community) could create a community HPC technical knowledge base that would allow us to share and reuse useful technical information. Much of these thoughts came out of discussions at the HPC Champions meeting that took place on 16 September 2019 alongside the UK RSE Conference 2019 in Birmingham, UK along with subsequent discussions at the monthly HPC RSE calls.
